Final answer:
An accurate answer regarding the specific percentage of sailors that must be C-WAY qualified is dependent on current U.S. Navy regulations, which could vary by command and operational needs.
Step-by-step explanation:
The question regarding what percentage of a command's eligible sailors must be qualified in Career Waypoints (C-WAY) pertains to specific military regulations or guidelines. While this is not classified under traditional academic disciplines, it deals with naval operational readiness and personnel management. Hence, giving an accurate answer requires up-to-date knowledge of the U.S. Navy's policies and directives regarding C-WAY qualifications.
As of the last knowledge update, the information regarding specific percentage requirements for C-WAY qualification in a command may not be publicly available or could vary depending on the specific needs and policies of a given unit. Commands must ensure that sailors are appropriately managed and retained according to their career milestones, which includes the use of C-WAY as a tool for maintaining operational readiness and career management.
Therefore, without the most current Navy personnel directives or instructions, it is advised to refer to current Navy guidelines or a command's personnel officer for the precise percentage. Remember, such information could be subject to change and might be considered sensitive within the context of naval operations.
